EBUS-TBNA Versus EBUS-TBNB

Endobronchial Ultrasound Transbronchial Needle Aspiration (EBUS-TBNA) Versus Endobronchial Ultrasound Transbronchial Needle Biopsy (EBUS-TBNB) in the Assessment of Mediastinal and Hilar Lymphadenopathy: a Randomised Trial

A prospective diagnostic clinical study randomising patients undergoing endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) of enlarged mediastinal and hilar lymph nodes to have sampling using the usual EBUS-TBNA needle or a novel biopsy forceps (EBUS-TBNB).

The study aims to establish whether the use of EBUS-TBNB can significantly increase the diagnostic yield over EBUS-TBNA, without an increase in complication rates.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The percentage of lymph nodes sampled resulting in a definitive diagnosis (as defined in the protocol) in the two study arms.
Time Frame: 18 months

The definition of a "definitive diagnosis" is dependant on the diagnosis and is clarified below:

  • Carcinoma/lymphoma: The lymph node sample is adequate to make a diagnosis as well as provide immunohistochemistry information enabling subtyping of the tumour.
  • Sarcoidosis: The presence of well formed epithelioid non-caseating granulomas.
  • Mycobacterial infection: The presence of caseating granulomas, positive Ziehl Nielson staining for acid fast bacilli, or the tissue successfully cultures Mycobacterium.
18 months

Secondary Outcome Measures

Outcome Measure
Time Frame
The difference in the complication rate between the two study arms
Time Frame: 24 months
24 months
